Hey Benny!

 BP> if i get a 10 meter long hdmi cable i could test it

is it 4k ?  I imagine something that size would make a difference compared to 1080p.  I don't have a TV, nevermind a 4k one, so you're on your own on this particular experiment.

 BP> and still have usb c ports to be used as monitors ports :=)

Exactly the same for the AsRock 4x4.

 BP> screens can be transportable, hehe

I am thinking more about in vehicle type applications, such as onboard boat computers.

 BP> so you miss firmware ?, or just a asus pn50 ? :)

I've got too much stinkin' firmware and no asus anything.  The asrock 4x4 is what is supplying the 4800U which matches your asus pn50.

 BP> also links -g https://localhost/mypicture.jpg :)

I use fbi for stuff like that.  I prefer links as a purely text based web browser.  Also I disable gpm mouse so that cutting text from links to a different console is doable.  That is far more productive than staring at meaningless graphics.  ;-)

 BP> i have a 49" android tv, cheap :=)

I don't know about android ones, but all the 4k TVs around these parts cost at least 3 times what a 1080p monitor does and is unlikely to fit into a mobile situation such as an in vehicle computer.

 BP> but it is expansive if it just a monitor, hmm

The 4k I have is just a monitor.  It is not noticeably better than a like sized 1080p monitor and is at least twice the cost.
 
 BP> rasberry pi 7" touch screen ?, i have one of them, still
 BP> planning on create something with it

I've seen those.  Personally I don't like touch screens but I do see them everywhere these days so apparently it is just me who avoids them.

 BP> yes it nice, olso on hollydays :=)

:-)  I like your spelling of holidays.

Life is good,
Maurice
